A damaged toilet stands amidst rubble in the town of Douma in eastern Ghouta of Damascus October 17, 2015. Some 2.4 billion people around the world don't have access to decent sanitation and more than a billion are forced to defecate in the open, risking disease and other dangers, according to the United Nations. The UN says that while there is sufficient fresh water on the planet for everyone, "bad economics and poor infrastructure" mean that every year millions of people - most of them children - die from diseases linked to poor sanitation, unhygienic living conditions and lack of clean water supplies. To mark World Toilet Day on November 19, Reuters photographers captured pictures of toilets in cities, towns and villages around the globe.
